, lumbus, in the county of Franklin and State I and part of the car.

of Ohio, have invented certain new and useful Improvements in Mountings for Wheels and Axles of Mine-Cars, of which the following is a specification, reference being had therein to the accompanying drawh1s invention relates to improvements in the devices for mounting the wheels and axles on the cars that are used in coalmines; and particularly to the cars of the class which have two wheels for each of two axles each axle being rigidly connected to one of its wheels and loose and rotatable in the other.

The object is to provide a set of parts for connecting the wheels and the axles to the cars, which parts together with the wheels and the axles shall be standard duplicates with relation to corresponding parts respectively, and which can be used upon either side of the car as occasion may require. When assembled the parts of a set are'simple in character, they being of such nature that they can be put together and taken apart at anyplace about the mine and at points remote from the shop without requiring skilled labor.

The axles in these car mountings as ordifrom one side to.the other in a way that I avoid.

In the drawings:

Fig. 2 is aside view of the wheel, the axle Fig. 3 is a vertical section taken transversely of the axle at the center of one of the boxes.

end to end. It is made from round. steel shafting, and the design of this and of the correlated parts is such that, it can be readily formed by merely cutting off sections or lengths such as are called for by the car and the track gage. It is not shouldered or provided with collars in the way fre-, quently followed, as it'has no direct bearing upon or contact with the bearings. It .is provided with two similar bores or apertures 4., one near each end. It is of such length that one end of the axle can project suitably beyond the outer planes of one of the wheel hubs, the end at 5 being somewhat nearer the center of the car than the end at 5 The wheels of the pair are indicated by 6 and 7, the one at 6 being secured rigidly to the axle by a bolt 9 passing through the hub 8 of the wheel and through the aper ture 4 in the axle. The wheel 7' is entirely loose on the other end of the axle, being held against displacement by a cotter key 10 or equivalent holder.

The curves in the tracks of coal mines are frequent and on short radii. The difli'erential travel, peripherally, of the wheels is very marked, and it is desirable to elimihate the slippage which is demanded of the narily made are of such nature that t hey inside wheel when the car is passing around such curves. At the same time it is desirable to have the axle rotate to distribute the wear the axle and wheels are made and connected in the We described the wheels rotate independent y and the axle 'is kept continuously in rotation by the wheel with which it is connected. I

Inasmuch as the axle is without shoulders or collars to engage with the inner sides of the' bearing boxes, the car and the boxes-sefcured thereto canadjust themselves laterally inward or outward as occasion demands. If the car moves onto a curve to the right the inertia carries the flange of the left hand wheel against its rail, and causes the car body with its loadto tend to move in the same direction. In the construction shown this tends to throw the pressure away from the right hand wheel and toward the flange and hub of the left hand wheel, there bein When 55 Y between the outer end of'the sleeve 18 and of the axle inside of the box. This pressure I provide for by replaceable washers such as shown at 24 and which are interposed between the left hand box and the hub. of

the left hand wheel, and between the inner end of the box and the inner end of the are duplicates for the right and left side of the car, they being indicated as entireties by 11 and 12. Each is formed of a cylindrical casing 13 with flanges 25 which are lated in the way described the wear from the relatively movable parts in the bearings is taken, as above explained, by the outer washer 24 and that at 20.

tools. It is merely necessary to draw the secured to the bottom 3 of the car by bolts 26; and at the inner end each has a closing wall 14 which is fitted as closely as possible to the axle; and at the outer end with a grooved flange 15. In the groove of this flange and in a groove or chamber in the endwall 14 are placed packings 17 and 16 to exclude dirt, grit and foreign material, and to avoid the escape of lubricant.

Within the casin 13 there is fitted a sleeve 18. This has a cy 'ndrical interior bore or chamber but is convexed on its outer face, the diameters of this outer face gradually shortening from the center, longitudinally, toward the end, and prevent any binding or bending of the axle. At the center the sleeve snugly contacts with the inner surface of the outer casing 13.

These mountings, as above stated, are secured to the wooden parts of the coal cars, and the boxes are apt tobe thrown out of correct alinement by the warpings and shrinkings of the wood. The axle carrying sleeves 18 compensate for: this as they permit the sleeves to rock around axes trans: verse to the axle and adjust themselves to the proper positions where the axle willv freely rotate. V In the chamber or space between the sleeves '18 and the axle are ,inserted ,rollers 21 in a continuous series loosely held in place. Between the inner end of the sleeve 18 and the wall, 14 of the bearing box there is inserted a replaceable washer, 20; and between this and the inner ends of the 'rollers 21 there is placed a washer ring 22 to take the wear and thrust of the rollers. The above specified replaceable washer 24 lies the inner end of the hub 8 of the wheel; and between this washer and the outer'ends of the rollers 21 there is a ring washer 23. Each sleeve 18 constitutes a thrust element by which the sidepressure of the car body is communicated to the outside washer 24 and thence to the wheel hub independently of the axle and of the rollers 21.

When the parts areconstructed and recotter. key at 10 and thereupon the axle can be drawn toward the left, its free end first passing inward throughthe right hand box and then outward through the left hand box. If the bolt 9 be withdrawn from the hub and axle the latter can be slipped also through the wheel. If any of the elements of a bearing require attention or replacing they can be readily drawn out and as readily replaced while the boxes remain in position on the car; and the wheels can be left in alinement if they and the car are properly supported, as by jacks.

If it is desired to reverse the shaft, endwise, as, when it 1s found that wear has occurred on the journal part of the loose wheel, it is inverted in position, that .is the end shown at the left is first passed through the left hand wheel and box and then through those at the right, the bolt is passed through the -'aperture previously holding the cotter key, and the latter 'is inserted in the. aperture previously holding the vboxes requires renewal it is a simple matter (while the axleis off) to withdraw the old washer, and insert a new one.
